I believe some Rohinga have been offered asylum in Saudi. But honestly I think the elephant in the room is in fact the Saudis. How directly they fund Isis I don't know, but there ideology has been exported wholesale and that certainly has fed into terrorism, both in the Middle East and Pakistan/Afghanistan. Yet there's Trump, hot on the heels of May kissing their arses and flogging them more weapons to blow up Yemeni children.
Meanwhile Trump points the finger at Iran who have done precisely nothing.
Then, if we cared so much about getting rid of IS we'd give a lot more backing to the Kurdish Pashmerga (Muslims too, in case anyone isn't aware) but of course can't be pissing off Turkey.
And that's without even factoring in the mess that is Syria.
The reality is that anyone could make a home-made device and detonate it in a crowd at any time. Or drive a truck into a group of people. What we rely on is people not wanting to.
And with the current global situation, and the selling of arms seemingly more important than human lives (as long as they are far away and brown), I don't see how terrorist incidents are going to decrease anytime soon.
